Ekuqaleni kwephrojekthi, ukufakwa kwesistimu yokufaka kubaluleke kakhulu. Ngokufunda lesi sihloko, uzofunda izinyathelo ezibalulekile namaphuzu okufaka uhlelo lwe-PV okunethemba lokuthi luzokusiza ekufakweni kwephrojekthi yakho yesikhathi esizayo.
Izingxenye zesistimu yelanga
1. Amaphaneli elanga
2. Uhlelo Lokufaka Ilanga
3. Ama-inverter
4. Ibhokisi lokuhlanganisa
Ukufakwa kwebhulakhethi
1. Ukuphambuka kokuma kwe-stent akudluli ku-±1mm ngemitha, kanti ukuphambuka kwe-engeli ye-stent akudluli ku-±1 degree. Ukufakwa kwe-bracket iyonke ukuqinisekisa ukuthi ikholomu yangemuva icocekile, igcina ubuso obuqondile kanye nobuso bokufaka, i-keel eyinhloko igcina ihambisana nobuso bokufaka.
Izimbobo zokufaka zemishini zezingxenye kufanele ziqinisekiswe ukuthi ziwela eduze kwama-keel amabili amakhulu, ngakho-ke uma ufaka i-bracket, qiniseka ukuthi isikhala phakathi kwama-keel amabili amakhulu e-bracket singu-867-1067mm.
2. I-Photovoltaic bracket isekelwe ngensimbi eyisicaba engu-40*4 mm egayiwe.
Izinyathelo eziyisishiyagalombili zokufaka ibhulakhethi endaweni ekhonkolo noma ophahleni oluyisicaba
1. Hlanza uphahla, ufake isisekelo, bese ulinganisa indawo yokufaka isisekelo usebenzisa itheyipu yokulinganisa ophahleni.
2. Bhabha imigodi esisekelweni sikasimende, ulinganise ukujula kwemigodi ngokusekelwe ekujikeni kwesisekelo kanye nobude bamabholidi ukuze kuqinisekiswe ububanzi bamabholidi obungu-M10. (Isisekelo ngaphambi kwamabholidi afakwe kusengaphambili ukuze kulungiswe ukungcola okusemicu).
3. Ukuqinisekisa ukuthi imigodi ihlanzekile, sebenzisa iphampu yokufutha ukuze ukhiphe ukungcola emigodini noma ukufuthe.
4. Faka amabhawodi okunweba emigodini bese uwafaka ngokucophelela endaweni yawo, ushiye isikhala esingu-30 mm phakathi kwebhawodi ngayinye, usebenzisa izando zokhuni noma izando ezingezona ezensimbi njengezando zesikhumba. Izando ezingenziwanga ngensimbi, njengezando zesikhumba, zingasetshenziswa ukunamathisela ibhawodi kancane emgodini oqhelelene ngama-30 mm.
5. Ukufakwa kogongolo noma isisekelo esingezansi, imigodi ihambisana namabholidi kanye ne-nut iqiniswe kusetshenziswa isikrufu (ngokuvumelana nendlela yokulungisa esinye isisekelo esishiwo ngenhla).
6. Amabholithi azosetshenziswa ukuqinisa isisekelo kanye nekholomu yangemuva ngokuhambisana ne-engeli lapho i-bracket izofakwa khona.
7. Uma ubopha imisebe evundlile, sebenzisa uxhumano lwe-engeli ukuze uqinise ikholomu yangemuva. Imisebe evundlile iboshelwa esisekelweni kusetshenziswa amabhawodi.
8. Bopha isisekelo kanye nomsebe ovundlile endaweni yawo.
9. Lapho nje i-keel isilungisiwe, kubalulekile ukukala ibanga phakathi kogongolo oluvundlile kanye nemikhawulo emibili yengxenye kusukela onqenqemeni bese ugcine isikhala esiphakathi kwe-keel kanye nemigodi yokufaka ku-±100mm.200–300 mm, qinisa i-keel ku-diagonal ngama-profile nuts.
10. Ukufaka ingxenye kuhilela ukulinganisa ukuphakama kwayo ngaphambi kokufakwa; ubuso bengilazi engezansi yengxenye bungama-300 mm ngaphezu komhlaba. Ukuze uqinise ingxenye, sebenzisa ibhlogo lokucindezela eliseceleni; qala uqinise ibhloko lokucindezela elingezansi ukuze uvimbele ingxenye ukuba ingasheleli; umngcele wengxenye ungama-20-30 mm ukusuka emaphethelweni e-keel. Ukuze uthole ukufana okuphelele kwengxenye, abantu ababili kumele basebenzisane ngesikhathi senqubo yokulungisa kanye nalapho besebenzisa irula lokulinganisa noma bedonsa indlela yomugqa.
Ukufakwa Kophahla Lwamathayela
1. Linganisa indawo yokufaka uphahla lwesisekelo sethayela le-ceramic ngokuhambisana nobukhulu obuboniswe emidwebweni, susa noma yimaphi amathayela afakwe ngaphambilini, bese usebenzisa izikulufo zokhuni ukubopha isisekelo ku-purlin yophahla (zama ukulungisa zonke izisekelo ngesikhathi esisodwa; uma izimo zikuvimbela, lungisa imigqa emibili ye-keel ukuze usize ekufakweni);
2. Ukufaka i-keel, ukulungisa isikhala se-keel ngokusekelwe lapho kutholakala khona imigodi yokufaka izingxenye ukuze kukhethwe i-keel kanye nemigodi yokufaka eqiniswe ku-± 100mm; kusetshenziswa amantongomane anephrofayili ngomshayo obekwe esisekelweni sethayela le-ceramic ukuze kulungiswe indawo yomngcele kusetshenziswa amabhawodi ayisithupha aqinisiwe;
3. Ukufakwa kwezingxenye: Ingxenye yokuqala izobekwa ohlangothini lwesitimela sokuqondisa. Usebenzisa irula, qiniseka ukuthi ukulingana komngcele wengxenye kulinganisa okungenani amamilimitha angu-20 ukusuka ohlangothini lwesitimela sokuqondisa. Okulandelayo, sebenzisa uhlangothi lwebhulokhi yokucindezela ukuze uqinise ukufakwa kwengxenye yesibili. Okokugcina, sebenzisa ibhulokhi yokucindezela ukuqinisa ibhulokhi yokucindezela usebenzisa indlela yokulungisa evundlile. Izingxenye ezisele zizofakwa kwenye indawo. Ukufakwa kwezingxenye ezisele kwenziwa ngokulandelana.
Ukufaka Amamojula
1. Imojuli kanye nendawo yokufaka kufanele kuhlukaniswe ngesikhala esingaphezu kwama-50 mm.
2. Amamojula kufanele ahlukaniswe ngama-20 mm.
3. Iphuzu eliphansi kakhulu le-PV module kufanele libe ngamamilimitha angamakhulu amathathu ngaphezu komhlabathi. Uma indawo ijwayelekile, kufanele okungenani ibe yi-1000mm ukugwema ukuchitheka kodaka nesihlabathi noma ukubhujiswa kwezilwane ezincane.
4. Kufanele kube khona okungenani u-10 cm phakathi kobuso bengilazi be-PV module ukusuka ebusweni bophahla.
5. Ukuze kuvinjwe ukuthi ibhloko yokucindezela eseceleni ingawi, i-keel kanye nezinhlangothi ezimbili ze-module zihlukaniswe okungenani ngama-20 mm.
6. Vikela i-keel bese uqinisekisa ukuthi iziphetho ezimbili zama-bezel e-module zingama-300-500 mm ukusuka ku-keel ngokulinganisa indawo yokufaka i-keel.
7. Ukuze kube lula ukufaka i-pressure block, ukuhlukaniswa kokuqala okuvundlile nokuqondile kwezingxenye ezimbili kungaphezu kuka-20 mm. I-pressure block izolungiswa uma isikhala esivundlile nesivundlile silungiswa sibe ngu-20 mm.
8. Ukuze kuvinjelwe ukuthi uhlangothi lwe-pressure block lungawi, kufanele kube nezingxenye eziyisishiyagalombili kuzo zombili izinhlangothi kanye ne-keel, ezihlukaniswe okungenani ngama-20mm.
9. Izingxenye kumele okungenani zibe ngamamilimitha angu-20 ukusuka ohlangothini lwesitimela esiqondisayo.
10. Izingxenye eziyishumi, ezihlukaniswe ngamasentimitha angu-50 ukusuka entanjeni yokuxhuma futhi ziboshwe ngezibopho.
11. izingxenye kanye nezingxenye zokufakwa kwebhokisi lokuguqula i-DC.
Ukufakwa kwebhokisi lokuguqula i-DC
1. Ukumelana nokufakwa kokushisa komhlabathi kwebhokisi lokuhlangana kwe-photovoltaic kanye neziphetho zalo zokufaka nezokuphuma kumele okungenani kube yi-2MΩ (DC1000V).
2. Ukuphakama kokufakwa kwe-inverter kufanele kufaneleke, lapho indawo yokuphuma (umshini uphezulu noma ohlangothini) ingu-400mm kanye nendawo yokungena ye-inverter (engezansi) ingu-600mm ukusuka phansi.
Ukufakwa kwezintambo ze-PV
1. Umugqa wengxenye emaphethelweni ngamunye, onesilinganiso sekhebula esingu-20-30 cm ukuvumela amakhanda ekhebula angu-2-3.
2. Umugqa wokukhishwa kwangaphambi komugqa wengxenye ye-PV: ngokusekelwe lapho ibhokisi lokuhlangana kwe-PV likhona, khipha inani elifanele kusengaphambili; akukho mfucuza yangaphambi kokukhishwa evunyelwe, futhi isethi ngayinye yokukhishwa kwangaphambi kokukhishwa ayikwazi ukuba yinde ngaphezu kwama-30 cm.
Ukufakwa kwesisekelo
1. Insimbi eyindilinga noma eyisicaba, okungcono ukuthi ibe nobubanzi obungu-8 mm, kufanele isetshenziswe njengentambo yokuhola phansi. Ubukhulu bensimbi eyisicaba akufanele bube ngaphansi kuka-4 mm, futhi ingxenye yayo evundlile akufanele ibe ngaphansi kuka-48 mm.
2. Insimbi egobile, ipayipi lensimbi, noma insimbi eyindilinga ingangcwatshwa enhlabathini yomzimba womhlaba oqondile wokwenziwa; insimbi eyisicaba noma insimbi eyindilinga ingangcwatshwa enhlabathini yomzimba womhlaba oqondile wokwenziwa. Idivayisi yokumisa umhlabathi eqondile yokwakha umhlabathi kufanele ibekwe ngaphansi kwengqimba ye-permafrost, futhi kuqinisekiswe ukuthi ukumelana komhlabathi kwesistimu yonke yokumisa umhlabathi akudluli ku-4Ω. Ububanzi bensimbi eyindilinga akufanele bube ngaphansi kuka-10mm; ingxenye yensimbi eyisicaba akufanele ibe ngaphansi kuka-100mm futhi ubukhulu bayo akufanele bube ngaphansi kuka-4mm; ukujiya kwensimbi ekhoneni akufanele kube ngaphansi kuka-4mm; ukujiya kodonga lwepayipi lensimbi akufanele kube ngaphansi kuka-3.5mm.
Ukufakwa kwama-inverter axhunywe kugridi
I-inverter kumele ifakwe endaweni ephakeme ehloniphekile. Indawo yayo yokungena engezansi ingu-600 mm ngaphezu komhlabathi, kanti indawo yayo yokuphuma eseceleni noma engenhla ingu-400 mm.
